Before you get started, make sure your PC is shut down. Then disconnect all the cables
from the back of the computer. Only begin this process when everything is
disconnected.
Remove the cover on the PC. After you identify a PCIe slot, unscrew the small metal
bracket attached to the computer case directly behind the PCIe slot. Gently yet firmly,
slide the video capture card into the PCIe slot, making sure it's fully locked down. Screw
the card into the back of the case so that the inputs and outputs are exposed on the
back of the computer case. Place the panel on the case, put the screws back in, and
stand the case upright. Plug all the cables back into the case. Power on the PC.
System will automatically recognize the game capture card, and you will see the device
name “ezcap Live Cam” in the Device Manager, which means that the device is ready
to work.
Note: We don't recommend using the device on Windows 7 system, but if you need,
please download the driver and install it.
